Yes Craig, you are absolutely right. I had to replace the other switch that controls the ECU. It was a year long nightmare because I didn't know where the fault was and I didn't know that switch existed. This switch was broken which meant that even without brake pedal pressure the circuit was always open although it should be closed without brake pedal pressure. I had no constant throttle and the engine died when accelerating. It was only with the help of other TMs that I found out what was wrong. Just in case your car does not drive well in this way later on, this switch, which is only opened when braking, is a possible and obvious source of error.
